PCS, a world first in disinfection

PCS, stable chlorinated products with neutral pH, a world first in surface disinfection.

Founded in 2012 by Larose and three Canadian partners, Process Cleaning Solutions (PCS) is exclusively dedicated to the research and development of cleaning processes and solutions that help to:

  • Protect public health
  • Protect the most vulnerable among us
  • Prevent the spread of antibiotic-resistant bacteria
  • Protect the environment


PCS cleaning and disinfecting solutions contain no volatile ingredients, contain only natural ingredients, and are unscented. All PCS non-disinfecting solutions and cleaning processes are certified by the Envirodesic™ certification program. An independent certification body, Envirodesic™ certifies products for maximum indoor air quality, minimal environmental impact and sustainability, including the ability to be used around chemically hypersensitive people.

In 2019, PCS introduced NPH technology, chlorinated, stable, pH-neutral products. A world first, for safe surface disinfection.

Unique to the PCS approach, the combination of PCS products and processes removes organic contamination from surfaces without depositing toxic chemical residues, unlike conventional disinfectants. (These residues can be more dangerous than the organic contamination that disinfectants are designed to remove).

PCS cleaning products and processes are not only suitable for hospital environments, they are also perfectly suited to the needs of senior residences, hotels, maintenance contractors, schools, daycare centers and public areas.

Following a scientifically proven cleaning process gives you the confidence that you are cleaning to protect health in the short term and making a lasting contribution to public health.

AIRx®, the science of smell, patented

AIRx®, the science of smell incorporated into cleaners, disinfectants and odor neutralizers.

Simply put, the unique concept behind AIRx® products is to combine the patented AIRICIDE® agent with malodorous molecules and change the size and shape of the molecules. When they reach the olfactory cilia, these transformed molecules are no longer perceptible as the original malodor.

The principle of the round peg in a square hole. Great!

Your sense of smell and the AirX of odor control

In an area less than 6 square centimeters in size, in a dead end on the roof of the nasal cavity, thousands of tiny hairs called cilia cause a thin film of mucus that covers the olfactory membrane to move in its middle. When air is sniffed, it is drawn into this area of the nose and molecules of odorous material are dissolved in the mucus. Just as we can only taste substances that will dissolve in the secretions of the mouth, we can only smell molecules that are dissolved in the moisture of the nose membrane.

The cilia are rooted in thousands of tightly packed cells with specialized chemoreceptors for odors spread between them. When the cilia transmit nerve impulses to the receptors, these in turn relay the impulses to the brain through the olfactory patch.

Beyond this point, the chemistry and physics of the sense of smell are not well defined. One theory claims that each of the thousands of cilia identifies only one specific odor. Another theory is that some cilia can identify a small group of “basic smells”, just as the eye sees “basic colors”. The brain then mixes these “fundamental smells” to form thousands of different smells.

In any case, it is assumed that a specific odor molecule fits a specific receptor, just as a round peg fits a round hole.  The AIRX concept of odor control has many aspects, but the basic concept is to use AIRX proprietary components to combine with odorant molecules and change their size and shape. Thus, when the transformed molecules reach the cilia, it is like trying to put a round peg in a square hole. So the molecule is no longer perceived as the bad smell it originally was.

The treatment for the relief of a foul odor may differ depending on the cause. So, while each AIRX product contains the unique AIRX Odor Neutralizer, which is part of the “round peg in a square hole” concept, each product also neutralizes odors in other ways. For example, it is obvious that whenever possible, the first step in eliminating a bad smell is to remove the source of the odor. AIRX products do just that. Some are in the form of absorbent material, others contain powerful germicides to kill putrefactive bacteria that will continue to emit foul odors until the bacteria are completely eliminated.

And while some manufacturers say their air fresheners do not contain masking odors, we do not hesitate to admit that AIRX blends do contain such odors. We believe that household and odor neutralizer combination products should leave a pleasant scent as a testament to the fact that the cleaning has been done.

All the products in the AIRx® line, more than 20 products, contain the patented AIRICIDE® agent. From surface cleaners, carpet cleaners, disinfectants, and bio-enzymatic products to microcellular blocks and absorbents. Everything you need to clean, disinfect and neutralize bacteria and odors in one step, whether they are in the air, on surfaces or underneath.

TGV, brilliant innovation for floors

TGV, a single floor finish, very fast drying, for all types of maintenance.
A brilliant innovation!

Floor maintenance is a laborious, costly and often complex task. Motivated to solve the problem, Larose has skillfully developed a floor finish that addresses the drawbacks of finishes on the market.

Reduce labor costs associated with application and drying time.

Unique on the market, the TGV finish, a very high speed drying formulation, allows to apply several successive coats in record time (5 coats in 60 minutes at normal temperature and humidity). Thus, even with limited time, it is possible to build a floor with a deep gloss, which ensures maximum protection and durability.

Create a finish that adapts to all maintenance methods and frequencies. Not the other way around.

No more need to have multiple floor finishes in the building to accommodate the maintenance frequency of the space in question and no need to adapt your polishing frequency to the whims of the floor finish.

In addition, depending on the traffic and your preference, TGV is available in 3 formulations, each offering unparalleled gloss, depth of shine and durability.
